As orthodox, you will probably get low piety generals as well, since they are trained in low zeal provinces, so that's not a problem. The issue arises only if there is a discrepancy between governor's piety and province's zeal.

edit: As Muslim, you can use the zeal for Jihads. Use imams to raise it.
